JOHL RYAN AND PATRICK RYAN, OF NEW YORK, N. Y.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 339,813, dated April 13, 1886.

Application filed January 14, 1886. Serial No. 188,611. (No model.)

To all whom it may concern:

Be it known that we, JOHN RYAN and PAT- RICK RYAN, both of the city, county, and State of New York, have invented a new and Improved Wrench, of which the following is a full, clear, and exact description.

The invent-ion has for its object to simplify the construction of that class of wrenches having a movable jaw adjustable by a screw; and to this end the invention consists in forming the handle of the wrench in two parallel contacting portions, one of which is provided with mortises to receive lugs on the other portion, all as hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of a wrench constructed in accordance with our invention. Fig. 2 shows a modified arrangement of the parts of the wrench. Fig. 3 is a cross-section on the line-o0 00 in Fig. 1. Fig. 4 is a crosssection on the line y yin Fig. 1.

in carrying out our invention we form the handle of the wrench in two parallel contacting parts, as shown in the drawings, forming in one of these parts the bearing for the outer end of the adjusting-screw for the movable jaw, and then by securing the two parts of the handle together, with the movable jaw and adjusting-screw in place, produce a complete wrench, which is composed of few parts, has strength for use, and is simple in manufacture.

in the drawings, A is the shank of the wrench, carrying the fixedjaw B, and on which the movable jaw C is arranged to slide. D is the adjusting-screw consisting of a threaded barrel working in and engaging a threaded recess in the movable jaw, and provided at its outer end with a pivot or journal, (I. Eis the handle of the wrench.

The handle E is formed in two parallel contacting parts, 0 6 extending the length of the handle, the part 6 being a prolongation of the shank A and the part 6 being shaped and fitted to the part c, to form therewith the complete handle, and a shoulder or abutment, k, for the screw D. A recess or aperture, f, for the pivot d of the screw is formed in the end or shoulder it of part e".

In Fig. 2 the construction is substantially the same, the parts being, however, differently arranged. The part c" is provided with tapering lugs g, to enter corresponding notches, h, in the part c by riveting down the projecting ends 9' of the lugs g, as in Fig. 2. The parts 6 e" are securely held together.

In the construction shown in Fig. 1 the recess f necessarily extends to the inner surface of the part c. In this case a half bearing box, in, can be used, but this is not essential.

It will be seen that there are but four really essential parts in this wrenchnainely, the shank A, fixed jaw B, and handle part c, forming one piece, the movable jaw, the adjusting-screw, and the part c of the handle.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-

A wrench having its handle formed in two parallel parts contacting throughout the length of the handle, one of which parts is a prolongation of the shank of the wrench, and which part is provided with mortises, and the other part of which handle is provided with lugs adapted to enter the mortises of the other portion, and in which latter portion the outer end of the adj ustingscrew isjournaled, as set forth.
